Unicode Frenzy!

Two Very Large Fonts: Code2000 and Code2001.

Enable support for surrogates in 2000/XP as follows:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\LanguagePack]
SURROGATE=(REG_DWORD)0x00000002

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\International\Scripts\42]
IEFixedFontName=Code2001
IEPropFontName=Code2001

(optionally)
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT CurrentVersionLanguagePack\SurrogateFallback]
Plane1=[Plane 1 Font Face name]
Plane2=[Plane 2 Font Face name] ...

(as explained here and here)

View your sparkly new fonts using BabelMap or True Type Explorer (both free, both lovely).

The ultimate authority is Unicode.org, and my sudden interest in the subject is all down to this blog.
